[Solved] How do I use Dapper.Contrib with FluentMap to update an entity with an identity column?

Maccurt Asks: How do I use Dapper.Contrib with FluentMap to update an entity with an identity column?
I have a class called Business, which has a property Id that is a identity field in MS SQL Server database. When I do an INSERT, it works properly. If I do the following:

Code:
_db.Update(business);

I get an error:

invalid column name ‘id” the column in the DB is BusinessId

I have mapped it to Id as below:

Code:
public class BusinessMap : EntityMap<Business>
    {
        public BusinessMap()
        {
            Map(x => x.Id).ToColumn("BusinessId");                
        }
    }

Now keep in mind my INSERT works. I tried adding the Key attribute to the class

Code:
[Table("Business")]
    public class Business {
        [Key]
        public int Id { get; set; }
        public string Name { get; set; }
        .....
    }

My work around (which I hate, but is better than nothing):
I decided to just call a SP to do this, which sort of sucks because I was hoping dapper could handle this.

Code:
_db.Query("BusinessUpdate",
                param: new { businessId = business.Id, business.Name, business.LocatorUrl, business.Website }, commandType: CommandType.StoredProcedure);

I don’t know why we are forced to conclude that every identity column in our database is named “ID”, that is ludicrous in my opinion, and I don’t think I need to justify my schema design, it should let me change it. Now anytime a field is added, I have to change the SP and the code to call the SP, I will use this until I found the real answer.
